A later Ford concept, the Mach II, has been described as a proposed Cobra successor, but the available sources do not establish that it was four-wheel drive. The distinction matters: the Mach II connection is supported, while the article’s original 4WD story is not verified.
How the Cobra began
Shelby American’s history says Carroll Shelby approached AC Cars after learning that the British company had lost its Bristol engine supplier. Shelby’s aim was to bring together European sports-car handling and an American V8.
The Shelby American Collection identifies CSX2000 as the first Cobra prototype. AC built it by modifying an AC Ace; after the car arrived in California, it received a Ford 260-cubic-inch V8 and a four-speed transmission.
The proposed Ford Mach II successor
MotorTrend describes the Ford Mach II as a proposed successor to the Cobra. Its account characterizes the car as a mid-engine concept assembled from rearranged Mustang parts, including a 289-cubic-inch V8 and front suspension positioned behind the two seats.

That description supports a mid-engine proposal, not a four-wheel-drive Cobra. The research available for this article does not verify the Mach II’s drivetrain, development status beyond the proposal, or whether it became a running prototype. It therefore cannot support the original article’s detailed claims about a 4WD Cobra mule, testing, performance, or engineering layout.
